QUASART — thermal insulation in Belval
Belval is one of the most emblematic urban conversion projects in Europe: a former 120-hectare ArcelorMittal steel site transformed into a new city since the early 2000s. Today, the site brings together the University of Luxembourg campus (Maison du Savoir, Maison des Sciences Humaines, Maison de l’Innovation), contemporary residential towers, student residences, the Belval Plaza shopping centre, the Rockhal and the preserved Blast Furnaces as industrial monuments. This mix generates diverse and demanding insulation needs.
New residential towers are typically insulated by high-density rockwool ETICS (fire resistance essential at height) or by ventilated facade with dissociated mineral insulation — the latter offering wide aesthetic choice for strong architectural signatures. University residences require strict thermal performance and strong acoustic demands (adjacent student housing). When the programme incorporates converted industrial heritage, QUASART collaborates with heritage architects on interior insulation (ITI) solutions compatible with preserving original brick and steel facades.
Our Crauthem (L-3327) head office is 20 minutes from Belval via the A13 motorway. Our teams work regularly on site projects — new developments, residences, university buildings, Belval Plaza shops. Logistics planned in a site where flows (students, residents, Rockhal spectators) must be preserved at all times.
Our insulation solutions
QUASART insulation solutions in Belval
StoVentec ventilated facades
Cladding on framework with dissociated mineral insulation — strong architectural signature, optimised durability and maintenance. Primary solution for contemporary Belval developments.
University residence insulation
ETICS plus interior acoustic linings for student residences — AAA thermal performance and indispensable phonic treatment between dwellings.
Industrial heritage — ITI
Interior rockwool or wood fibre lining for converted buildings (former steel halls, factory offices) — preserves the identity of brick and steel facades.

FAQ
Frequently asked questions — Insulation in Belval
Belval residential towers impose three constraints: AAA thermal performance (R ≥ 5.0 m·K/W on the envelope), fire resistance (A2-s1,d0 classification mandatory from 28 m height), and architectural signature compatible with the site master plan. Reference solutions: high-density rockwool ETICS (140-200 mm) with reinforced mineral finish, or StoVentec ventilated facade with dissociated mineral insulation 160-200 mm. Both system families are present on existing Belval towers.
Yes. QUASART can work on Belval university buildings and student residences — Maison du Savoir, student residences, campus annexes. These programmes require strict thermal performance (certified campus), strong acoustic treatment (adjacent student housing), and impeccable site conduct in an environment frequented by students and the public. Our teams are prepared for these constraints.
Converted Belval steel buildings (former halls, offices, technical premises) often feature facades with strong heritage value — brick, metal sheet, exposed steel — that the architectural project aims to preserve. In these cases, external ETICS is excluded: ITI (interior insulation) is preferred, with rockwool or wood fibre lining on metal framework. Particular attention goes to moisture management (adapted vapour barrier, respect for hygrothermal transfers between old wall and lining).
Both solutions are valid, the choice depends on priorities. Thin-render ETICS: controlled cost (180-280 €/m²), wide palette of tints and finishes, proven installation. Ventilated facade (StoVentec type): higher cost (300-500 €/m²), very strong architectural signature (natural stone, ceramic, composite), durability > 50 years, simplified maintenance (demountable elements), identical thermal performance. On Belval, both families coexist depending on architectural choices.
For a typical new Belval development (tower or residence), ETICS budget brackets vary widely by system. Rockwool ETICS plus reinforced render plus silicate finish: 180-280 €/m² installed. HPL or ceramic cladding ventilated facade plus mineral insulation: 300-500 €/m². Natural stone ventilated facade: 450-800 €/m². For programmes targeting BREEAM or DGNB, add 10-20% extra linked to bio-based systems and additional environmental studies. Accurate pricing after project study.
The Belval master plan, led by the Fonds Belval, defines an architectural framework that strongly guides choices on each plot — massing, volumes, facade materials, relationships to public spaces. Developers and architects submit their project for validation before the building permit. ETICS finishes are therefore often guided by this framework — no garish tints, favouring noble and durable materials. QUASART integrates these constraints from the start of pricing.
